Want to be spiritual? Be yourself. I've been taught that my self is bad and to be spiritual I have to be all these good things that I'm not.
i agree that i'm not sure that it means you have to be all these good things, i mean, i guess the bible will say you have to be all these good things, but to me it is more about trying to be good, and if being yourself encompasses this, then i agree with what you say, it is about being good to yourself, and not at the expense of others. Even further, it is about helping others without any benefit to yourself.
Sometimes, you must not also only look at the bad things that people do in their lives (not to say that you should look at the good things, and not to say that you should release them of guilt) but also look at intention, now intention, in an immediate respect, can mostly be sinful is the outcome is bad, but the picture of intention, reaction, can differ extremely. One of the books i read, speaker for the dead, takes this approach to looking at the lives of people, i found it fascinating to see how the writer Orson Scott Card looked at the things people do, and how people can look at these things in order to quench that internal turmoil that exists.
